We show that repeated-root cyclic codes over a finite chain ring are in general not principally generated. Repeated-root negacyclic codes are principally generated if the ring is a Galois ring with characteristic a power of 2. For any other finite chain ring they are in general not principally generated. We also prove results on the structure, cardinality and Hamming distance of repeated-root c...

Before effective anti-poverty policy can be designed and implemented, the extent, trend and distribution of poverty must be identified. In this sense, poverty measurement is a crucial intermediate step in public policymaking and development planning. This paper asks whether the estimated proportion of the world’s population with income below US$1 (adjusted according to purchasing power parity) ...

The transition to a low carbon economy demands new strategies for maintaining competitiveness and benefiting from ‘green growth’. A network of stakeholders offers opportunities for, as well as constraints to, organisational growth and successful low carbon strategies. This multiple-case study explores the relational dynamics between the case organisations and a range of stakeholders. We find th...

We theoretically and numerically study the influence of both instantaneous and Raman-delayed Kerr nonlinearities as well as a long-wavelength pump in the terahertz (THz) emissions produced by two-color femtosecond filaments in air. Although the Raman-delayed nonlinearity induced by air molecules weakens THz generation, four-wave mixing is found to impact the THz spectra accumulated upon propaga...

The purpose of this study was to examine the relationship between vertical jump measures and sprint speed over 10, 20, and 40 m in professional basketball players. Thirty-three professional basketball players aged (±SD) (27.4 ± 3.3 years), body mass (89.8 ± 11.1 kg), and stature (192 ± 8.2 cm) volunteered to participate in this study. All participants were tested on squat jump, countermovement ...

The construction of power algebras is an important way for producing new algebras from the given ones. Much information about an algebra can be derived from that concerning its power algebras, and it is interesting to treat the questions such as: What structural properties of A are inherited by its power algebras, and to what extent does the structure of power algebras of A determine that of A?...

Cross cultural IS Research is beginning to mature, however, much is left to do. This research-in-progress paper reviews the most popular conceptualization of National Culture and offers suggestions for improvements in measurement. While Hofstede’s measures, consisting of uncertainty avoidance, power distance, masculinity/ femininity, and individualism/collectivism, are still widely used in many...

By use of the Gold map, we construct a partition of the hypercube into cosets of Hamming codes that have minimal possible pairwise intersection cardinality. Let m ≥ 3 be odd and let F be the finite field GF(2) of order 2. Let σ be a power of 2, and assume that σ± 1 and 2− 1 are relatively prime (that is, both x → x and x → x are one-to-one mappings), which is, by simple arguments, equivalent to...

this study aims to examine how iranian efl learners perceive and apply mitigation devices in request speech act in 4 asymmetrical situations. role-play interactions and questionnaires were used to elicit the required data from iranian informants (male vs. female). the results obtained from the analysis of data revealed that in identical situations, male requestors were comparably more certain t...

the purpose of this study is to examine the possible impact of value systems on earnings management in france, tunisia and canada. cultural values include power distance, uncertainty avoidance, individualism, masculinity and long-term orientation. the cross-cultural study uses the method of structural equations trough lisrel approach. the examination covers the period between 2003 and 2009. fin...
